See what Phuket weather looks like for the next 36 hours and whole week, but remember that weather forecasts often appear quite dramatic. As you probably already know, there are two seasons in Phuket: the high season is from December to April and the rainy season is from May to November. Each year is different, and the weather in Phuket is known to be very unpredictable. Some years, the rainy seasons can be beautiful with many blue sky days, and the next, there will be a lot more rain. Because of this, no one will ever promise you anything when it comes to the weather in Phuket.
